sqlalchemy SKILL.md skillA
sqlalchemy from codeatcode/oss-ai-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add codeatcode/oss-ai-skills/sqlalchemy@v3.0.0Pins v3.0.0 in mdr.lock. Pin the fingerprint instead.

Use when working with SQLAlchemy 2.0 in Python - declarative models, queries, sessions, async engines, Alembic migrations, relationship loading strategies, N+1 detection, pool exhaustion, or 2.0 migration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> **Objective:** Use this skill to prevent N+1 query bugs, session lifecycle errors, and connection pool exhaustion in data layers by enforcing relationship loading strategies, transaction boundaries, and async patterns.
# SQLAlchemy
Python SQL toolkit and ORM. See [official docs](https://docs.sqlalchemy.org/en/20/) for full API reference.
## Installation
```bash
pip install sqlalchemy[asyncio] alembic
pip install asyncpg # PostgreSQL async driver
pip install psycopg2-binary # PostgreSQL sync driver
```
## Engine and Pool Configuration
```python
from sqlalchemy import create_engine
# Basic engine
engine = create_engine("postgresql://user:pass@localhost/db", echo=True)
# Production pool settings
engine = create_engine(
"postgresql://user:pass@localhost/db",
pool_size=10, # Base connection pool
max_overflow=20, # Max extra connections under load
pool_timeout=30, # Wait time for connection
pool_recycle=3600, # Recycle connections after 1 hour
pool_pre_ping=True, # Check connection health (critical for pool exhaustion fix)
echo_pool=True, # Log pool events for debugging
)
```
### Async Engine

How to install
mdr add codeatcode/oss-ai-skills/sqlalchemy@sha256:6daf634d98a15397The line at the top of this page pins the label v3.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
